I've never been a huge fan on Windows (more into Linux myself now), but I decided to try the RP of Win 8 after a small disaster with the Dev Preview.
I like using it on my main laptop without a touch screen and on a touch enabled device? It's going to be awesome.
I was skeptical at first but I love the new design of this like Metro. Anyone with some time to kill and a spare PC should try it out while it's free.
